Claims
- 1. An improved homogeneous, high-softness, high-bulk cellulosic one-ply facial tissue product of the type comprising a wet laid web of cellulosic fibers wherein the improvement comprises selecting the cellulosic fibers incorporated in the furnish for said web such that:(a) at least 20 percent by weight of the fibers in the web have a coarseness exceeding 23 mg/100 m; (b) at least about 20 percent by weight of the fibers in the web have a coarseness of less than about 12 mg/100 m; and (c) the weight average coarseness to length ratio of the fibers in the web is less than about 8.5 mg/100 m/mm.
- 2. The one-ply facial tissue of claim 1 wherein the weight-weighted average fiber length of the fibers in the web is greater than about 1.75 mm.
- 3. The soft, one-ply facial tissue product of claim 1 having a serpentine configuration and a basis weight of at least about 12.5 lbs./3000 sq. ft. ream and having low sidedness, said single-ply absorbent paper formed by conventional wet pressing of a cellulosic web, adhering said web to-a Yankee dryer and creping the web from the Yankee dryer, said absorbent paper including:(a) a temporary wet strength agent comprising an organic moiety, and (b) nitrogenous softener agent, the amount of the temporary wet strength agent, and the nitrogenous softener added being sufficient to produce a one-ply facial tissue having a serpentine configuration and a specific total tensile strength of between 40 and 200 grams per 3 inches per pound per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 20.0 grams per 3 inches per pound per 3000 square feet ream, the ratio of MD tensile to CD tensile of between 1.25 and 2.75, a specific geometric mean tensile stiffness of between 0.5 and 3.2 grams per inch per percent strain per pound per 3000 square foot ream, a friction deviation of less than 0.250, and a sidedness parameter of less than 0.30.
- 4. The one-ply facial tissue of claim 3 wherein the absorbent paper product exhibits a specific total tensile strength of between 40 and 150 grams per 3 inches per pound per 3000 square foot ream a cross direction specific wet tensile strength between 2.75 and 15 grams per 3 inches per 3000 square feet ream, a specific geometric mean tensile stiffness of between 0.5 and 2.4 grams per inch per percent strain per pound per 3000 square feet ream, a friction deviation of less than 0.250 and sidedness parameter of less than 0.30.
- 5. The one-ply facial tissue of claim 4 wherein the one-ply facial tissue exhibits a specific tensile strength between 40 and 75 grams per 3 inches per 3000 square feet ream, a cross direction specific wet tensile strength of between 2.75 and 7.5 grams per 3 inches per pound per 3000 square feet ream, a specific geometric mean tensile stiffness of between 0.5 and 1.2 grams per inch per percent strain per pound per 3000 square feet ream, a friction deviation of less than 0.225; and a sidedness parameter of less than 0.275.
- 6. The absorbent facial tissue of claim 1 wherein after creping, the web is optionally calendered and wherein the web is embossed between mated emboss rolls, each of which contain both male and female elements.
